Q-link don't work in arranger window

Ho guy!

Why I can’t use the q-link mode (shift+alt) in arranger Window?
If I select many tracks and I want muted, I Press shift+alt+CLIC on “M” in One track. But the mute Is Active only in une track.

In the mixer Window work correctly

Thanks for tour help

Not sure but I normally just press M to mute all selected tracks.

Thank you… I Will try It when I come back at home

Work perfectly… I’m a stupid.

Thank you!!!
